You would have something like this, using lumped models: gap k12 k23 +--o o--+ +-----+-----+ +------+ | | | | | | | C1 L1 L2 C2 L2' L3 C3 | | | | | | | +-------+ +-----+-----+ +------+ This circuit behaves exactly as a "magnifier", where instead of a direct connection from the top of L2 to the base of L3 there is a transformer L2'-L3. I have done an analysis of this configuration, and didn't see particular problems, or advantages. A set of design formulas can be derived from the design formulas for a magnifier: http://www.coe.ufrj.br/~acmq/tesla/magnifier.html I can post the formulas for this configuration, if there is interest. C2 can be omitted, and then the circuit is equivalent to a regular Tesla coil with a different link between primary and secondary, but then parasitic capacitances at the connection can't be absorbed.
